Project description:Obstruction in any part between the outlet of the bladder and the external urethra is called partial Bladder outlet obstruction (pBOO), which is a common disease in urology, which may cause bladder dysfunction. We have comfirmed that human urine-derived stem cells (hUSCs) could improve the bladder function of pBOO rats in our previous study. We thus explored the role of miRNAs in pBOO rats before and after treatment of hUSCs, and revealed that they could serve as effective prevention and treatment therapeutic targets. Rat bladder tissues were used for miRNA sequencing. We identified 8 differentially expressed miRNAs in the pBOO rats before and after treatment of hUSCs.

Project description:Colorectal cancer is the second most common cancer by the site in Europe and the third most common cancer in the USA with high morbidity and mortality. Survival after the treatment has improved over the past few decades as a result of early diagnosis, radiotherapy, and advances in surgical techniques such as abdominoperineal resection (APR), low anterior resection (LAR) and total mesorectal excision (TME). These innovative surgeries are the current standard treatment for the mid and the low rectal cancers which avoids the permanent colostomy. It is very difficult to find out the incidence of the bowel, bladder and sexual dysfunction of patients either because they are embarrassed or because they do not relate their symptoms to rectal cancer treatment. This article reports the incidence of the bowel, bladder and sexual dysfunction following surgery for rectal cancer from the National Academy of Medical Sciences, Bir Hospital, a tertiary level hospital.

Project description:Bladder cancer (BCa) is one of the most common malignancy of the urinary tract. In order to improve the diagnosis, prevention and treatment of BCa, the details of molecular mechanisms underlying the tumorigenesis and development needs to be clarified. Results provide insight into molecular mechanisms underlying the mRNA and miRNA interactions in BCa. 3 human bladder cancer tissues and 3 normal bladder tissues were analyzed using microarray. The alteration of mRNA and miRNA expression between the 2 groups were detected.

Project description:Background: MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression. Their abilyty to affect multiple gene pathways by targeting to various mRNAs makes them to an interesting class of regulators. The interplay between miRNA and mRNA has been proposed as an important process in cancer development and progression. In this study, we analyzed miRNA -mRNA interactions in bladder urothelial carcinoma. Methodology/Principal Findings: We have developed a new algorithm which is capable of identifying altered miRNA-mRNA regulation between tissues samples without preexisting stratification of groups. Microarray expression profiling of both miRNA and mRNA from the same sample were performed using a collective of 24 urothelial carcinoma and normal bladder tissue samples. Using our approach, normal and tumor tissue samples as well as different stages of tumor progression were successfully stratified. Also, we were able to analyzed individual miRNA-mRNA interactions from each patient, focusing on different miRNA families. Conclusions: Just recently, the need for tools that allow an integrative analysis of microRNA and mRNA expression data has been addressed. With this study, we provide an algorithm that considers the special nature of miRNA induced regulation and shows good specificities and sensitivities when applied to bladder cancer expression data. mRNA and microRNA expression data were analyzed together to identify bladder cancer specific micoRNA-mRNA interaction

Project description:In the development and progression of bladder cancer, there are many genetic changes. We established a SD rat orthotopic bladder cancer model through intravesical instillation of N-methyl-nitrosourea and pathologic diagnosis is bladder transtional cell carcinomal (BTCC). We used microarrays to analysis the gene expression changes among these rat bladder carcinoma, adjacent normal tissues and bladder tissues of normal rats. Three paired tumor tissues (Group A) and adjacent normal tissues (Group B) were obtained from 3 SD rats with BTCC, and 3 normal tissues (Group C) obtained from 3 normal SD rats. Affymetrix microarrays analyzed the gene expression changes among above 3 groups of tissues.

Project description:Bladder cancer is one of the most common malignancy in the urinary tract with high recurrence and drug resistance in clinics. Alternative treatments from existing drugs might be a promising strategy. Nitazoxanide (NTZ), an FDA-approved antiprotozoal drug, has got increasingly noticed because of its favorable safety profile and antitumor potential, yet the effects in bladder cancer and underlying mechanisms remain poorly understood. Herein, we find that NTZ induces mitochondrial damage and mitophagy initiation through PINK1-generated phospho-ubiquitin(pS65-Ub) and autophagy receptor-mediated pathway even in the absence of Atg5/Beclin1. Meanwhile, NTZ inhibits lysosomal degradation activity, leading to mitophagy flux impairment at late stage. Mitochondrial reactive oxygen species (ROS) production is critical in this process, as eliminating ROS with N-acetylcysteine (NAC) efficiently inhibits PINK1 signaling-mediated mitophagy initiation and alleviates lysosomal dysfunction. Co-treatment with NTZ and autophagy inhibitor Chloroquine (CQ) to aggravate mitophagy flux impairment promotes NTZ-induced apoptosis, while alleviation of mitophagy flux impairment with ROS scavenger reduced cell death. Moreover, we also discover a similar signaling response in the 3D bladder tumor spheroid after NTZ exposure. In vivo study reveals a significant inhibition of orthotopic bladder tumors with no obvious systemic toxicity. Together, our results uncover the anti-tumor activities of NTZ with the involvement of ROS-mediated mitophagy modulation at different stages and demonstrate it as a potential drug candidate for fighting against bladder tumors.

Project description:Bladder outlet obstruction (BOO) causes lower urinary tract symptoms and objectifiable urodynamic changes in bladder function. We carried out an integrated transcriptome and proteome analysis of bladder samples from male patients with BOO before and 3 months after de-obstruction surgery (transurethral resection of the prostate, TURP). mRNA and protein profiles were correlated with urodynamic findings, specifically voiding detrusor pressure (PdetQmax) before TURP. Patients with high PdetQmax showed less advanced remodeling and inflammatory changes than those with lower values. We oberved significant dysregulation of gene expression, which was reversed by de-obstruction in both patients’ groups. We propose a series of biomarker genes, indicative of BOO, and possibly contributing to the bladder changes. Our data sheds light on the stages of progressive obstruction-induced bladder decompensation, and might add selecting the operation point to avoid the loss of contractility.

Project description:Patients treated with radiotherapy to the chest region are at risk of cardiac sequelae, however, identification of those with greatest risk of complications remains difficult. Here, we sought to determine whether short-term changes in circulating miRNA expression are related to measures of cardiac dysfunction in follow-up. miRNA expression analysis in the primary group showed marked changes in serum miRNAs immediately after RT compared to baseline. miRNAs with increased expression correlated positively with cardiopulmonary dose-volume histogram metrics, while those with decreased expression exhibited negative correlations.
